From the abstract:
Despite closures being over twice as likely to occur in the Republican-controlled states that did not expand Medicaid, closures were associated with reduced support for federal Democrats and the Affordable Care Act following local closures. I show that rural voters who lost hospitals were roughly 5–10 percentage points more likely to vote Republican in subsequent presidential elections. If anything state Republicans seemed to benefit in rural areas from rejecting Medicaid and resulting rural health woes following the passage of the ACA.


To multiple the problem. Rural people will come to the city hospitals that are already overwhelmed and put more pressure on them.
